One option is the original R4DS. You can get one for ~$3 from Priceangels or NDSCardsale. It has good build quality, good compatibility by using WoodR4. It won't work on the DSi and doesn't support SDHC microSDs. But pretty much the best value you can get.
CycloDS is great as far as build quality, features and support goes. But overpriced, imo.
why would you mention the R4DS? not only is it a very old flashcart, newer games don't work with it anymore, it's no longer offcialy updated either, there is a very high risk of getting a clone too.
Because some people really like Wood R4.
the cyclo ds is priced that way for a reason and it is worth every penny, you get frequent updates for newer games, high quality build flashcart supports SDHC (which the original r4ds doesn't unless you buy a clone) it has real time save, great skins available for it, battery saver mode, and all sorts, very good flashcart.
The things you just mentioned are on many different flashcarts. The CycloDS is very over-priced, and it's bound to die soon if Team Cyclops don't reconsider the price.
QUOTE(milkbot @ Jun 24 2010, 11:55 AM) At first I thought Supercard DSTWO, because of all the snazzy features, but reading the review to it it didn't seem too much different from the M3i in terms of a flimsy feeling card, freezing issues, features which aren't quite upto par etc etc.
